Abstract
In an apparatus for scanning a transverse region of moving web, the speed of the web being scanning adjusts the clock of the camera that controls the scanning rate of the camera, to maintain a constant spacing of the scan regions, rather than vice versa, thereby allowing wide variations in web speed while maintaining constant scan region spacing. Additionally, the intensity of the web illumination is controlled as a function of web speed so that each scan region receives the same amount of light from the illumination means during each scan interval regardless of variations in web speed.
